a) Calculate the rotational energy
difference, in cm-1, between the J=1 and J=3 energy
levels of a nitrogen molecule. The isotope mass, in amu, is
14.0031. The nitrogen molecule bond length is 109.76 pm.
b) Calculate
the translational energy difference, in
cm-1, between the 3,3,3 and the 4,3,3 energy levels of a
nitrogen molecule confined to a cube with sides equal to 1.0
micron. The isotope mass, in amu, is 14.0031. Do not use
reduced mass!
